After accusing the recipient of "talking crazy" about him and suggesting ways to kill herself, Hernandez explains he has a TV in his cell and watches all the Patriots games.

"And yes I still root for my squad and still love all the ones I loved," the letter reads. "The closest I was with was probably Brady in whom I love to death and always will and only hope the best for them."

Hernandez says he still supports the team even though some — including Kraft — no longer support him.

"And fake a-- non loyal Kraft who told me he loved me everytime he seen me but obviously shows his word ain't s--- but my love was real and still love all them cuz I'm not a phony like many of them!" the letter says. "But I watch every game faithfully cheering them on and always will cuz I have love for so many of them!"

Hernandez is serving a life sentence after being convicted last year of the 2013 murder of semi-professional football player Odin Lloyd.

He has also been indicted in the 2012 killing of two Boston men, whom Hernandez is accused of gunning down after a chance encounter at a nightclub. He has pleaded not guilty. A trial date has not yet been set.
